The concept of 'cognitive load' refers to the amount of mental effort required to process information. In educational psychology, cognitive load theory (CLT) suggests that learning is most effective when instructional design minimizes extraneous load, allowing working memory to focus on intrinsic load and germane load. Intrinsic load is the inherent difficulty of the material, while germane load involves the mental resources dedicated to constructing and automating schemas. Research has shown that overly complex presentations, such as redundant text and visuals, can overwhelm learners, hindering retention. Conversely, well-structured materials that segment information into manageable chunks can enhance understanding. However, critics argue that CLT often overlooks individual differences, such as prior knowledge and motivation, which may modulate the impact of load. Thus, while CLT provides valuable guidelines for educators, its application requires careful adaptation to diverse learner profiles.
❓ According to the passage, which of the following best summarizes the main argument regarding cognitive load theory?

C. C) Intrinsic load is the only factor that determines learning effectiveness.
D. D) Critics believe that cognitive load theory is irrelevant to modern education.
✅ 正确答案
B) The theory emphasizes reducing extraneous load but must be tailored to individual learner differences.
